Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 85,826,465, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 85,826,465 | |
| -1 | -85,826,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,826,465.
Example:
1 x 85,826,465 = 85,826,465
and
-1 x -85,826,465 = 85,826,465
Notice both answers equal 85,826,465
With that explanation out of the way, let's continue. Next, we take the number 85,826,465 and divide it by 2:
85,826,465 ÷ 2 = 42,913,232.5
If the quotient is a whole number, then 2 and 42,913,232.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 85,826,465 | |
| -1 | -85,826,465 |
Now, we try dividing 85,826,465 by 3:
85,826,465 ÷ 3 = 28,608,821.6667
If the quotient is a whole number, then 3 and 28,608,821.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 85,826,465 | |
| -1 | -85,826,465 |
Let's try dividing by 4:
85,826,465 ÷ 4 = 21,456,616.25
If the quotient is a whole number, then 4 and 21,456,616.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 85,826,465 | |
| -1 | 85,826,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 73 | 235 | 365 | 3,431 | 5,003 | 17,155 | 25,015 | 235,141 | 365,219 | 1,175,705 | 1,826,095 | 17,165,293 | 85,826,465 |
| -1 | -5 | -47 | -73 | -235 | -365 | -3,431 | -5,003 | -17,155 | -25,015 | -235,141 | -365,219 | -1,175,705 | -1,826,095 | -17,165,293 | -85,826,465 |
